BR 6747-1NC

BR® 6747-1NC

BR® 6747-1 NC primer is a one-part, modified epoxy primer which contains no volatile organic compounds (VOCs). This non-chromated material is 100% water-based and does not rely on exempt solvents to achieve its zero VOC level rating. It exceeds all state and federal VOC emission regulations for structural adhesive bonding primers and offers mechanical properties and corrosion resistance equal to that of solvent-based primer systems. In addition, BR® 6747-1 NC provides outstanding performance with most 250°F (121°C) - 350°F (177°C) curing adhesive systems. Service temperature is from -67°F (-55°C) to 350°F (177°C).

BR® 6747-1 NC offers wide application/processing latitude, simple processing with High Volume Low Pressure (HVLP) or standard air atomizing spray equipment and is insensitive to spray booth conditions - temperatures from 65°F - 90°F (18°C - 32°C) and relative humidity from 30% - 70%. Typical applications for BR® 6747-1NC include bond primer for aluminum components where corrosion protection is critical, corrosion inhibiting paint primer for aluminum substrates, and effective adhesion promoter for other metals (stainless steel, titanium, and nickel).
